The GEN II controller is designed for uto hangeover, multi-stage Heat Pump (2/3H) and Gas Electric (2/2H) applications. The GEN II system uses the Zonex ModStat, which modulates and controls the ST series, 3-wire, 24-volt, power open / power close round and rectangular dampers. Sophisticated, integrated software allows for a wide range of system control and changeover strategies, allowing the contractor to tailor the GEN II system to your specific application. dditional features include LED status indication of all system functions, digital LT display, fully adjustable capacity control with on-board limit settings, and optional staging strategies. Night setback operation is standard, with selectable 2-hour override at each stat, along with a unique feature to remotely lock thermostats in the system. The system provides the installing contractor with a simple startup diagnostic to minimize wiring errors and speed installation. GEN II is recognized as the Industry s easiest commercial zone control system to install and wire. The GEN II system operates over an unshielded two-wire data link, along with two 24v power wires all daisy chained from stat to stat with no home run wiring required. Three wires from the stat to actuator control a modulating damper in each zone. The GEN II system does not require a computer to set up or operate. 1

6 GENERL SEQUENE OF OPERTION GEN II offers the following additional control features: Set ooling and Heating capacity cut-out set points nd djustable timing to initiate 2 stage operation djustable opposing call changeover timing Priority demand votes on a stat-by-stat basis Provide default occupied and unoccupied set points on every stat utomatically open all dampers for air balancing GEN II components: GEN II controller (includes integrated capacity control) Zone thermostats Modulating power open / power close 24vac supply dampers Modulating power open / power close 24vac bypass damper with static pressure control ommunication cable (elden 8740) twisted pair or Zonex supplied equal Time lock 24vac 40va transformers: 1 to control system and all supply dampers 1 for bypass damper and static pressure control GENERL SEQUENE OF OPERTION When the GEN II controller is powered up, the total number of addressed thermostats (ModStats) are determined and verified on the display. This confirms the controller is communicating with all thermostats in the system. If there are no active heat or cool calls detected, the supply dampers will modulate to 40% open for ventilation mode. The system blower operation can be configured for constant ON or intermittent uto. The controllers are shipped from the factory for uto fan. The GEN II systems can be field configured for adjustable time based opposing call changeover, vote based majority changeover, or priority vote changeover by thermostat assignment. The GEN II controller is shipped from the factory for 10-minute opposing call changeover. The GEN II controller polls the thermostats once per minute to determine the thermostat demand status for heat and cool. The heat and cool changeover functions will operate by the type of changeover selected on the controller. When the GEN II controller changes modes, a 5-minute purge cycle is initiated before the changeover is completed. On active heat or cool calls, the non-calling zones will modulate to the closed position. When the last calling zone is satisfied in either heat or cool mode, the GEN II controller terminates the HV outputs after the next poll and the blower output will be de-energized (unless controller is configured for constant fan) for a 5-minute purge cycle. During the purge cycle no heat or cool calls are recognized. When the system is in the heating mode and calls for cooling are received, an opposing call timer strategy operates. This timer is adjustable from minutes. The factory default is 10 minutes. t the end of the selected time period, if the opposing call is 3 away from set point, heating is turned off. fter a 5-minute purge mode, ooling is turned on until the cool call is satisfied. If necessary, GEN II will return to the heating mode, If all calls have been satisfied, dampers will modulate to the 40% open position for ventilation. If the opposing zone strategy is not desired, this feature may be disabled. This mode may be enhanced by adding Priority votes to each thermostat in the system, thereby weighting certain zones more than others. This Priority mode allows you to select 0, 1, or 2 additional votes for a thermostat that has unusual loads, like a conference room. Minimum / Maximum damper positions can be set to provide ventilation. Each thermostat has uxiliary contacts support and control a supplemental heat source i.e., baseboard, reheat, or hot water coil, to meet the temperature requirements of any commercial application. 2

29 SYSTEM STRT UP ND TEST System Start Up and Test 1. Plug all thermostats into sub-bases. Turn GEN II power switch (E) to ON. 2. Find the first Thermostat in the Daisy chain and change its address from 20 to 001. (See ModStat installation instructions onfiguration ddressing). 3. Turn GEN II power switch OFF and then ON. The Display should flash 01 and then show the leaving air temperature. This confirms your successful wiring and communication with that thermostat. 4. If 01 is displayed, change the next thermostat s address from 20 to 002. Turn the GEN II power switch OFF and then ON. Th e display should flash 02 and then show the temperature. Readdress thermostats one at a time. 5. fter each stat is re-addressed, turn the power switch off and then on. This will verify that the re-addressed stat has been found by the GEN II ontroller. This procedure will simplify your installation and will confirm your wiring is correct and that the GEN II controller can communicate over the 2-wire twisted pair data link with every thermostat in your system. Troubleshooting When stat #1 is not found: 1. heck thermostat to verify that it is addressed as heck all and wiring for proper color-to-color connections. Even if the stats are lighted, all wires at the thermostat must be connected to the GEN II terminal. ll wires must be connected to the GEN II terminal. onfirm the daisy chain wiring is correct at this time. 3. heck,, & wires for proper color code and connections; polarity is imperative. ll connections must land on terminal on the following thermostat, and all connections must connect to terminal on each thermostat, and all connections must connect to terminal on each thermostat if used. 4. heck and wires for opens or shorts. hecking the Daisy hain for opens or shorts: Start from the GEN II board, and follow,, & wires to the first sub-base. Remove the,, & wires going to the next sub-base in the link. Plug a stat into the first sub-base, and address it as #1. Turn the GEN II power switch Off, then On, to see if the display flashes 01, at the GEN II controller. 1. If 01 is displayed, the first link of the daisy chain is OK. Reconnect the wires going to sub-base. 2. Repeat these steps with a stat numbered 02. If the number 02 is displayed, then communication is confirmed. When the correct number does not appear for a link, that link is either shorted or open. link of the daisy chain, which is open or shorted, must be repaired before the next thermostat is checked. When the thermostats are correctly addressed, wired and linked, the total number of stats on your job connected to the GEN II control board will be displayed when the board is turned on. fter the correct number of connected thermostats is displayed, complete the wiring of the unit or heat pump connections, next make heat and cool calls to the GEN II controller. 25

30 DVNED FETURE ONFIGURTION Occupied / Unoccupied fan operation The factory setting for FN operation is UTO, with the FN jumper (I) on the middle and lower pins. In this setting, the fan circuit on G is only energized on an active cool call in Gas/Electric mode or on an active heat call or cool call in Heat Pump mode. This applies to both Occupied and Unoccupied modes. When the FN jumper is in UTO, there is no output on G with an active heat call in Gas/Electric mode. onstant Fan in the Occupied (DY) mode Place the FN jumper (I) on the center and upper pins on ON. The fan output on G will be constant in the Occupied (DY) mode and will revert to auto in the Unoccupied (NIGHT) mode. Opposing all hangeover The GEN II controllers are configured at the factory for Opposing all hangeover with a time delay setting of 10 minutes. With this configuration, any number of thermostats can make a like active call (heat or cool). During this time, if a single thermostat makes an opposite call, a timer is started at the next poll. This timer starts a time delay operation to allow the initial calling thermostats to satisfy. If the initial active thermostats do not completely satisfy after 10 minutes, the dampers all close and the controller drops out the HV outputs and goes into a 5 minute purge cycle. When the purge cycle times out, the opposing thermostat call is initiated; and the appropriate HV outputs are energized, and the supply damper opens. The thermostat with the opposing call must now satisfy before the GEN II controller will recognize any of the initially calling thermostats. The opposing call timer is factory adjusted for 10 minutes. However, the delay time can be field adjusted from 5 to 30 minutes, or disabled. To increase the opposing call time delay: 1. Press the SET and UP buttons. 2. Release the SET button when the display changes, and continue to hold down the UP button. 3. Release the UP button when the desired time is displayed. To lower the time delay: 4. Press the SET and UP buttons. 5. Release the SET button, and immediately press and hold the DN (down) button until the desired time is indicated; then release. The Opposing all feature can be disabled by performing steps 1 through 3 and then releasing the UP button when the display indicates 32. With this feature disabled, the GEN II controller will operate changeover by majority vote from the zone thermostats. Priority active Heat and ool call operation The GEN II controller may be configured in the field for majority vote changeover but also assign multiple votes for selected thermostats to enhance the changeover operation for special requirements. Each thermostat represents one vote for heat or cool operation; a majority of active calls will determine which mode the controller will operate in. With the Priority feature, any thermostat may be assigned one or more additional votes to allow it to have priority to bring a mode changeover more quickly. To keep proper overall temperature control, this priority vote change should be limited to as few zones as possible. Follow the procedure to implement Priority vote operation: 26

31 DVNED FETURE ONFIGURTION 1. Determine which thermostat address is to have an additional one or two votes. 2. Place the PRIORITY jumper (F) on both pins. 3. Press and hold the SET and UP buttons (H), and the LED display will scroll through the number of zones starting with When the display indicates the address (01 to 17) of the thermostat you want to add votes to, release both buttons and press the DN button. The display will scroll through 00, 01, 02. To add one additional vote, release the DN button when the display indicates 01 (this assigns a total of 2 votes). To increase the votes by two, press the DN button and wait until the display indicates 02 and then release the DN button (this assigns a total of 3 votes maximum). 5. To change the votes back to a single vote, press the DN button on the selected address and release when the display indicates To review the vote status of all of the thermostats in the system, press the UP button; and the display will first indicate the address number starting with 01and then the vote status for that address. 00 = 1 vote 01 = 2 votes 02 = 3 votes. Upon review, if stat #1 has 2 votes, the display will show Stat 01 followed by 02 signifying the number of Priority votes assigned to Stat 1. Stat 02 will appear followed by a blank display, indicating only 1 vote; and Stat 03 will appear followed by a blank screen, indicating no priority votes have been added to Stats 02 or e certain to Place the PRIORITY jumper on one pin to put the controller back into normal operation with the changes that were made. Thermostat security - Set Point LOK The GEN II system provides the ability to electronically lock all of the zone thermostats (global). When the thermostats are in the LOK mode, there will be a padlock icon on each thermostat display. The LOK mode limits the manual changing of the heat and cool set points to a maximum of 2 above or below the initial heat and cool set point temperatures. To set the thermostats for the LOK mode, simply change the switch position (K) from UNLOK to LOK. ll of the thermostats will change to LOK on the next system poll. To unlock, set the switch to the UNLOK position; and the thermostats will drop the icon after the next system poll and revert to normal operation. ir alance - Force Dampers Open When performing an air balance on the supply air outlets, the GEN II controller provides a unique feature to simplify this procedure. The GEN II controller will put all thermostats in a cool call which will open the dampers 100% and bring on the system blower. 1. Place the EH jumper (F) over both pins 2. Press the SET and UP buttons (H) simultaneously This puts a global cool set point of 58 F (14 ) on all of the zone thermostats, and the controller energizes the G fan output only; Y1 is not energized. 3. When the air balance procedure is completed, press the SET and DN buttons simultaneously, which will assign 70 F (21 ) Heat and 75 F (23 ) ool set points on all of the zone thermostats. 4. Press and hold the SET and DN buttons; and while holding these buttons, remove the EH jumper tab and place it on one pin. Release the SET and DN buttons.

The following procedure will provide a 75 F (23 ) ool and 70 F (21 ) Heat occupied set point along with Unoccupied 58 F (14 ) Heat and 85 F (29 ) ool set point for every thermostat in the system. This handy feature minimizes visits to the thermostats. To establish these default set points: EH jumper (F) - place the jumper over both pins. Press the SET and DN button (H) simultaneously to engage default set points. Remove the EH jumper, and place on one pin to put controller back into normal operation. To view the unoccupied set points place the Night / Day switch (L) to the NIGHT position. Following a poll, the thermostat backlights will turn off; and the unoccupied set points will be displayed.

For accurate selection use duct sizing table or D-FUSER ZONE DMPER Zonex Systems D-Fuser is a combination zone damper and diffuser. It mounts in a standard 2 x 2 T-bar ceiling opening, providing for simple installation and easy maintenance access. The D-Fuser is a cone shaped fluidic nozzle with a platen that modulates up and down to control air flow. s the platen moves up, the air volume is reduced; but the air velocity and throw remain constant. This keeps the air hugging the ceiling, which maximizes room air mixing and minimizes the waterfall effect. The D-Fuser is a fully modulating power open / power close damper using a 24vac 60Hz 2 V motor. Motor drive time from full open to full close is 90 seconds. The D-Fuser connects to round duct either on the side or top. ollars are available for 6, 7, 8, 9 and 10 duct. 12 OLLR: PLE ON SIDE PLE ON TOP T NEK VELOITIES UP TO 700 FPM N LESS THN Neck Vel P FM Throw 50 FPM Neck Vel P FM Throw 50 PM Neck Vel P FM Throw 50 FPM

36 SIZING ZONE DMPERS SIZING ZONE DMPERS If the ductwork already exists, simply size the damper to fit the ductwork. For new systems or retrofit jobs:. Determine FM from heat gain or loss calculations.. Select damper size using either the round capacities chart, the rectangular capacities chart or by using a duct sizing table or calculator.. Select a Zonex Systems damper to fit the duct size selected for that zone. Make sure your zone dampers match the type specified in the table showing Maximum Differential Pressure. INSTLLTION NOTES 1. Do not exceed 700 FPM in a register/diffuser branch duct. 2. If a damper is installed within 3 feet of a register/diffuser, install sound attenuating flex duct between damper and outlet. 3. Zone dampers should be preceded by 2 4 of straight pipe where possible. 4. In attic installations and high humidity areas, the Zonex Systems damper should be insulated along with the ductwork. The hat section on the round damper is delivered with insulation between the hat section and pipe. Therefore, insulation should be applied to the round pipe and be butted against the hat section (do not insulate the motor). The motor generates enough heat so that no condensation will develop on it. 5. Remember to allow a 16 gap in the duct for heavy duty rectangular dampers. 6. Medium pressure rectangular dampers slide into a 3¼ wide cutout in the side of the preexisting ductwork. 7. Minimum open and close positioning is field adjustable on the actuator. The damper is shipped from the factory to close 100%. NOTE: Dampers should not be installed with motor upside down in the 6:00 position. SLVING UP TO THREE ZONE DMPERS Up to three dampers can be directly controlled by one zone thermostat. To wire two or three dampers for a zone, use the following wiring diagram.

37 YPSS DMPERS- ELETNI ELETNI YPSS DMPERS ypass dampers are used to provide constant air delivery through the air handling unit. This is done by bypassing excess air from the supply duct back to the return duct. s a zone is satisfied, its zone damper closes. When this happens, the bypass damper opens just enough to bypass the excess air. This will control static pressure and noise at the diffusers. The Electronic ypass Damper is used on any size system over 5 tons. The damper can be round (STP) or rectangular (STDP) with integrated static pressure control; and multiple dampers can be slaved together. SIZING ELETNI YPSS DMPERS The bypass damper is to be sized for the total system 1500 FPM. System FM should be calculated at 400 FM per ton. Example: 5-ton system is rated at 2000 FM (5x400 = 2000). When calculated at 1500 FPM, the bypass damper should be 16. Never undersize the bypass damper.

NOTE: Multiple round dampers can be slaved from one static pressure control to provide the correct capacity. One large rectangular bypass damper may be used instead of multiple round dampers. See below. RETNGULR YPSS DMPER SELETION The Zonex Systems STDP WxH damper is used for rectangular bypass applications. These dampers are also sized for the total system FM rated at 1500 FPM.

40 INTEGRTED PRESSURE ONTL SETUP ypass Damper with Integrated Pressure ontrol is used to control bypass operations. The bypass damper modulates to maintain static pressure as zone dampers open and close. The bypass system reduces air noise from the supply registers caused by excessive air velocity. If the system is configured for intermittent fan mode and the system satisfies, there will be a 3-minute delay to allow for system purge, after which the bypass damper will open to 25%, preventing noisy rush of air through supply registers when fan starts up on a call for heat or cool. If the system is configured for fan continuous operation, the STP (Round) or STDP (Rectangular) Electronic ypass will monitor static pressure continuously, providing constant control of system static.
